Reef Status™ Strontium

  • 50 titration tests for strontium
  • Only 10 minutes per test!
  • Precise results in 0.5 mg/L increments
  • Easy test validation with included reference

Strontium occurs in natural seawater at a concentration of about 8 to 10 mg/L. It is chemically very similar to calcium, and many organisms incorporate it in their skeletons along with calcium. Its addition to reef aquariums aids the growth of corals, coralline algae and other organisms that lay down a calcereous skeleton or shell, including tridacnid clams.


50 Tests

Reef Status™ Strontium is capable of at least 50 strontium determinations and is designed specifically for seawater.



Measures between 5 mg/L and over 50 mg/L strontium


Detectable changes in 0.5 mg/L increments.

Reference Sample

It isn't necessary to run a reference test to use this kit; however, its proper performance can be validated by running a test in the normal manner except that the reference sample is used in place of aquarium sample. You might choose to run a reference test if you have cause to believe the test is giving incorrect results.

The 10 Minute Strontium Test

The first and only 10 minute strontium test! The test involves separation of strontium from the sample by a highly selective extraction technique, followed by a sensitive titration in 0.5 mg/L increments. The sample is treated and filtered through an adsorbent to selectively remove the strontium from solution. The filtrate is discarded and the adsorbent is washed to remove residual sample. The strontium is then eluted from the adsorbent and measured.

KEEP AWAY FROM CHILDREN! This kit is not a toy. It contains reagents that may be hazardous if used carelessly or contrary to instructions. Strontium #1 is a very strong acid, use extreme caution when handling, always keep capped when not in immediate use and do not remove from the test kit box. In case of contact rinse affected area thoroughly with water. In case of spills neutralize with a strong baking powder solution (or any pH raising buffer). The Sr Indicator Reagent #2 should pose no immediate hazard. Strontium #3 is a strong caustic similar to drain cleaner. Strontium #4 should pose no immediate hazard. Strontium #5 is strongly acidic. The Strontium Adsorbent in the separation column should not be removed. The Titrant is a buffered chelating solution with antimicrobial preservatives. Do not get reagents in eyes, on hands, or clothing. Do not drink or swallow any reagents. If eye contact or swallowing occurs with any reagent, seek medical attention. In case of discomfort or doubt, seek medical attention.
